摘要
对HK40炉管焊接易产生热裂纹及保证800℃左右使用的热强性及热稳定性,提出了保证焊缝质量的措施,通过焊接试验与评定,确定了施焊工艺,并成功地用于转化炉管的焊接。
In allusion to the welding of HK40 stovepipe easily brings hot crack and ensures the high temperature strength and stability about 800 ℃,takes measures to ensure welding quality.Also confirms the electrodes and welding technologies by welding test and procedure qualification,successfully used on the welding of transfer stovepipe.
